<h3>Transformation Mode</h3>
<p>
In this mode a curve can be rotated, moved and scaled, as long as the
respective parameter <a href="#Rotate"><i><code><span data-if="hdevelop" style="display:inline">Rotate</span><span data-if="c" style="display:none">Rotate</span><span data-if="cpp" style="display:none">Rotate</span><span data-if="com" style="display:none">Rotate</span><span data-if="dotnet" style="display:none">rotate</span><span data-if="python" style="display:none">rotate</span></code></i></a>, <a href="#Move"><i><code><span data-if="hdevelop" style="display:inline">Move</span><span data-if="c" style="display:none">Move</span><span data-if="cpp" style="display:none">Move</span><span data-if="com" style="display:none">Move</span><span data-if="dotnet" style="display:none">move</span><span data-if="python" style="display:none">move</span></code></i></a> and <a href="#Scale"><i><code><span data-if="hdevelop" style="display:inline">Scale</span><span data-if="c" style="display:none">Scale</span><span data-if="cpp" style="display:none">Scale</span><span data-if="com" style="display:none">Scale</span><span data-if="dotnet" style="display:none">scale</span><span data-if="python" style="display:none">scale</span></code></i></a>

</p>
<ul>
<li>
<p>  To move the curve, click with the left mouse button on the cross
in the center and then drag it to the new position, i.e., keep
the mouse button pressed while moving the mouse.
</p>
</li>
<li>
<p>  To rotate it, click with the left mouse button on the arrow and
then drag it, till the curve has the right direction.
</p>
</li>
<li>
<p>  Scaling is achieved by dragging the double arrow. To keep the
ratio, the parameter <a href="#KeepRatio"><i><code><span data-if="hdevelop" style="display:inline">KeepRatio</span><span data-if="c" style="display:none">KeepRatio</span><span data-if="cpp" style="display:none">KeepRatio</span><span data-if="com" style="display:none">KeepRatio</span><span data-if="dotnet" style="display:none">keepRatio</span><span data-if="python" style="display:none">keep_ratio</span></code></i></a> has to be set to

</p>
</li>
</ul>
<h3>Edit Mode</h3>
<p>In this mode, the curve is displayed together with its control polygon.
Start and end point are marked by an additional square and the point which
was handled last is surrounded by a circle representing its weight. You can
perform the following modifications:
</p>
<ul>
<li>
<p> To append control points, click with the left mouse button in the
window and a new point is added at this position.
</p>
</li>
<li>
<p> You can delete the point appended last by pressing the Ctrl key.
</p>
</li>
<li>
<p> To move a point, drag it with the mouse.
</p>
</li>
<li>
<p> To insert a point on the control polygon, click on the
desired position on the polygon.
</p>
</li>
<li>
<p> To close respectively open the curve, click on the first or on
the last control point.
</p>
</li>
<li>
<p> You can modify the weight of a control point by first clicking on the
point itself (if it is not already the point which was modified or
created last) and then dragging the circle around the point.
</p>
</li>
</ul>
<p>Pressing the right mouse button terminates the procedure.
</p>
